FIELD: measurement technology. SUBSTANCE: device has power supply, strain gage bridge, differential amplifier, analog-to-digital converter, microprocessor, and read-only memory. Additionally introduced in device are digital temperature sensor, temperature corrector, identifier, inverter, adder, comparator, and display and keyboard unit. In the course of device operation temperature dependence of strain gage bridge is corrected and alarm operates in case input pressure rises to threshold value. EFFECT: enhanced measurement accuracy, enlarged functional capabilities. 1 dwg
